6 Rules for Using a Space Heater Safely

Never plug a space heater into an extension cord as a long-term solution Space heaters draw 12-15 amps, and most extension cords can’t handle that sustained load. The cord overheats, melts, and can start a fire.

If you must use an extension cord temporarily, choose a 14-gauge or thicker cord A lower gauge number means thicker wire. Keep the cord as short as possible.

Check the cord temperature regularly during use If the cord feels warm to the touch, stop using it immediately. A warm cord means it’s overheating.

Never plug a space heater into a power strip, surge protector, or multi-tap These devices are not designed for high-current loads and will overheat or fail.

Never run the extension cord under a rug or through a doorway Covering the cord traps heat and increases fire risk. Damage from foot traffic or doors can also cause shorts.

Plug the space heater directly into a wall outlet whenever possible Move the heater closer to the outlet instead of using an extension cord. Your house is worth more than a few feet of convenience.
